The Brief International Cognitive Assessment in Multiple Sclerosis (BICAMS): Validation in Arabic and Lebanese Normative Values.

OBJECTIVE: Multiple sclerosis (MS) is often associated with cognitive deficits. Accurate evaluation of the MS patients' cognitive performance is essential for diagnosis and treatment recommendation. The Brief International Cognitive Assessment in Multiple Sclerosis (BICAMS), widely used cognitive testing battery, examines processing speed, verbal and visuospatial learning, and memory. Our study aims to examine the psychometric properties of an Arabic version of the BICAMS and to provide normative values in a Lebanese sample. METHOD: The BICAMS, comprised of the Symbol Digit Modalities Test (SDMT), Brief Visuospatial Memory Test-Revised (BVMT-R), and a newly developed verbal learning/memory test, the Verbal Memory Arabic Test (VMAT), were administered on healthy subjects and MS patients. The sample consisted of 180 healthy individuals, of whom 63 were retested after 2-3 weeks. Forty-three MS patients matched with 43 healthy subjects based on age, sex, and years of education were assessed. A sample of 10 MS patients was also examined on two occasions. Test-retest reliability and criterion-related validity were examined, and regression-based norms were derived. RESULTS: The test-retest correlations showed good evidence of reliability with coefficients ranging between 0.64 and 0.73 in the healthy sample, and between 0.43 and 0.92 in the MS sample. The BICAMS was able to discriminate between MS patients and matched healthy participants on the SDMT and BVMT-R. Normative data were comparable to other studies. CONCLUSIONS: This new Arabic version of the BICAMS shows initial good psychometric properties. While good evidence of VMAT's reliability was shown in the healthy participants, less test-retest reliability in this tool was seen in the MS group, and partial criterion-related validity was evident. This renders further examination of the VMAT. We provide regression-based norms for a Lebanese sample and encourage the use of this battery in both research and clinical settings.

Validation of the Cognitive Reserve Index Questionnaire (CRIq) in Arabic.

Cognitive reserve is the adaptability of cognitive processes in the face of brain aging and pathology. This study aimed to validate the Arabic version of the Cognitive Reserve Index Questionnaire (CRIq) in a healthy Lebanese sample. CRIq assesses cognitive reserve through three domains: education, working activity, and leisure time. Statistical measures, including descriptive and regression analysis along with structural equation modeling, were utilized to investigate the convergent and discriminant validity of the CRIq, incorporating fluid intelligence (Gf) and measures of cognitive function, long-term memory encoding and retrieval (Glr), and processing speed (Gs). Results from 174 participants revealed that the activities assessed by the CRIq-Arabic were comparable to the original CRIq study, with slight cultural differences. The internal consistency of the CRIq-Arabic was good (Cronbach's α = 0.88), indicating reliability. Convergent validity was confirmed, with moderate to high loadings on the cognitive reserve latent construct. Discriminant validity was supported as correlations between cognitive reserve variables and non-target constructs (Gf, Glr, and Gs) were less than 1. The findings provide an initial psychometric validation of the CRIq-Arabic. Further research of clinical samples is needed to enhance its utility in neuropsychological practice.

Results from the first culturally tailored, multidisciplinary diabetes education in Lebanese adults with type 2 diabetes: effects on self-care and metabolic outcomes.

OBJECTIVE: Diabetes self-management education (DSME) is an essential component of lifestyle management needed for diabetes care. This pilot-study tested the effect of culturally-tailored education targeting diabetes selfcare on glycemia and cardiovascular risk factors of Lebanese with type 2 diabetes mellitus (T2DM) (n = 27; Age: 61 ± 10 yrs, 59% males, HbA1c: 8.98 ± 1.38%). RESULTS: Diabetes self-care (Diet, Self-Monitoring Blood Glucose and foot care) improved after 6 months, which was reflected in a significant drop in glycemic levels (HbA1c:-0.5%; FPG: - 38 mg/dl), and cholesterol/HDL ratio (4.45 ± 1.39 vs. 4.06 ± 1.29). Waist circumference decreased at 6 months compared to 3 months (p < 0.05). This is the first effective culturally-tailored intervention that improved self-care, glycemic control, body adiposity and lipid profile of Lebanese with T2DM. Larger scale implementation with representative sample is warranted.

Mental health in Lebanon: Tomorrow's silent epidemic.

Lebanon is a middle-income country that has been recently crippled by several tragedies including the economic collapse, COVID-19, and the fourth of August Beirut port explosion, the world's most powerful non-nuclear explosion of the twenty-first century. Recent data on mental health from Lebanon is summarised, and other topics such as the psychological impact of cumulative adversities and the role of international support in Lebanon are examined. Data from Lebanon shows severe levels of distress among the people, in a country with minimal resources. Given current adversities in Lebanon, recent data in the country, and the literature on adversity and mental health outcomes of man-made disasters, Lebanon is most likely going to face an epidemic in poor mental health. A call is made for the wider scientific community and international organizations to support the mental health field in the country and help prevent further negative mental health outcomes. Understanding how to better navigate mental health in places with extreme adversity and emergencies can be beneficial to other communities which might face similar challenges.

Development, psychometric properties, and pilot norms of the first Arabic indigenous memory test: The Verbal Memory Arabic Test (VMAT).

BACKGROUND: Tests of verbal memory (list learning) are particularly useful for clinicians and researchers globally, yet there are no psychometrically robust tests that are built indigenously for Arabic-speaking populations, which comprise more than 370 million. OBJECTIVE: To develop a verbal memory Arabic test using a systematic procedure of item selection and then provide evidence of validity and reliability in an Arabic-speaking sample in Lebanon. METHOD: In study 1, we conducted a word prototypicality study (n = 77), and identified 932 words across 7 semantic categories. Following quantitative analyzes and qualitative judgments by an expert panel, we selected a sufficient number of words and categories, and constructed and piloted the items, instructions, and protocol for the Verbal Memory Arabic Test (VMAT). In study 2, we administered the VMAT on a community sample (n = 199; screened for depression and cognitive impairment) and patients with Multiple Sclerosis (n = 16). RESULTS: Scores decreased with age as expected, they discriminated well between healthy and clinical populations (matched on age, sex, and years of education), and showed acceptable consistency within items and across time. Conclusions: The VMAT is the first Arabic test developed indigenously. It can be used in clinical and research settings with Arabic-speaking populations to assess verbal learning.

Serum vitamin D level is associated with speed of processing in multiple sclerosis patients.

Multiple Sclerosis (MS) is often associated with low serum 25(OH)D levels, as well as cognitive dysfunctions. The relationship between 25(OH)D and the most commonly affected cognitive domain in MS; processing speed, is poorly explored. The purpose of this study is to: (1) assess the effect of serum 25(OH)D change on processing speed in MS, and (2) explore the relationship between serum 25(OH)D and brain volume changes in MS. A retrospective chart review was conducted, data from 299 patients were extracted (baseline), of whom 163 had follow-up measurements (after at least a 9-month interval). The Symbol Digits Modalities Test (SDMT) was used as a measure of processing speed. MRI data was available from 78 individuals at baseline, and 70 at follow-up. SDMT scores and brain volumes (Cerebellum (total, grey, and white), intracranial, Grey Matter (GM), and White Matter (WM)) were compared based on 25(OH)D levels and their changes towards follow-up. Results indicated that patients with deficient 25(OH)D levels had lower SDMT scores when compared to those with sufficient levels, and SDMT scores improved as a function of 25(OH)D. For MRI measures, only patients with sufficient 25(OH)D levels during both assessment periods had significant changes in intracranial and total cerebellum volumes. We conclude that 25(OH)D levels seem to have an effect on processing speed in MS, thus the importance of clinical monitoring and supplementation in this regard is reinforced.

Factors affecting MS patients' health-related quality of life and measurement challenges in Lebanon and the MENA region.

BACKGROUND: In the Middle East and North Africa (MENA) region, few studies explored the quality of life of multiple sclerosis patients and the factors affecting it. OBJECTIVE: The objective of this study was to explore studies on multiple sclerosis quality of life in the MENA area through a comprehensive literature review. To validate the Multiple sclerosis international Quality of Life (MusiQoL) and Modified Fatigue Impact Scale (MFIS) in Arabic, and investigate the impact of sociodemographic and clinical variables of Lebanese multiple sclerosis patients on quality of life. METHODS: As part of an ongoing observational prospective research study, data from 663 stable multiple sclerosis patients were analysed. RESULTS: In Lebanese multiple sclerosis patients, the Arabic MusiQoL and MFIS seem to be accurate and valid tools with high reliability coefficients and confirmatory factor analytic indices. Variables such as age and disease type predicted multiple sclerosis quality of life, yet were significantly affected by psychosocial fatigue. The influence of sociodemographic and clinical variables on quality of life dimensions varied. Being a woman with multiple sclerosis, receiving medications and experiencing physical fatigue worsens the psychological wellbeing quality of life dimension. CONCLUSION: Several sociodemographic and clinical variables predicted the health-related quality of life dimensions of multiple sclerosis patients in MENA. Further in-depth investigation to guide more targeted clinical management is recommended. We encourage using validated multidimensional tools to measure quality of life in MENA such as the Arabic MusiQoL.

Cognitive Reserve Factors in a Developing Country: Education and Occupational Attainment Lower the Risk of Dementia in a Sample of Lebanese Older Adults.

Background: Dementia secondary to neurodegenerative diseases is prevalent among older adults and leads to social, psychological and economic burden on patients, caregivers and the community as a whole. Cognitive reserve factors such as education, and mental stimulation among others were hypothesized to contribute to the resilience against age-related cognitive impairment. Educational attainment, occupation complexity, physical activity, and leisure activity are explored in the context of protecting the older adults' cognitive function. We investigated the cognitive reserve effect on dementia, cognitive decline and impairment, and global cognitive function. Methods: This study is a secondary analysis of data from a cross-sectional, community-based cohort study that aimed at investigating factors associated with dementia and their prevalence. The sample was of 508 community based older adults in Lebanon, aged 65 years and above in addition to 502 informants designated by these older adults. Older adults and informants answered structured questionnaires administered by interviewers, as well as a physical assessment and a neurological examination. Older adults were diagnosed for dementia. Global cognitive function, depression, and cognitive decline were assessed. Results: Older adults with dementia had lower levels of education, and attained lower occupational complexity. Factors such as high education, complex occupation attainment, and leisure activity, significantly predicted better global cognitive function. An older adult who attained high education levels or high complexity level occupation was 7.1 or 4.6 times more likely to have better global cognitive function than another who attained lower education or complexity level occupation respectively. Conclusion: These results suggest that cognitive reserve factors ought to be taken into consideration clinically during the course of dementia diagnosis and when initiating community-based preventive strategies.

Rey Figure Test with recognition trial: normative data for Lebanese adults.

OBJECTIVE: This study aimed to provide normative data for four trials of the Rey figure Test - a complex design used to assess visuoconstructional abilities, aspects of visual memory, and aspects of executive functioning. Despite its frequent clinical and research use in the Arab region, published studies regarding the measures' adaptation or normative data remain absent. METHOD: We administered the Rey figure on a convenience sample of Lebanese (n = 254) aged 30 years to 99. RESULTS: We examined the impact of relevant demographics, and found that age, gender, and years of education impacted scores, and norms were derived based on these variables. Such normative data for the Rey figure enhance its practicality and psychometric adequacy for use in research and clinical settings in Lebanon.

Effect of 7-minute workout on weight and body composition.

BACKGROUND: The 7-minute workout composed of aerobic and resistance exercises is becoming a very popular workout. It targets individuals with time constrains and low motivation to commit to lengthy and extensive workout programs. The objective of the study is to investigate if the 7-minute workout has a 6 week effect on body weight and composition. METHODS: The training group (N.=29, age 18-30) did the 7-minute workout 7 days a week during 6 weeks while the control group (N.=29) did not perform the workout. Measurements such as height, weight, body mass index, circumferences (middle upper arm, hip, and waist), blood pressure, heart rate, hand grip, and bioelectrical impedance were collected and recorded at week 1, 3 and 6. RESULTS: Mean BMI was 24.4kg/m2 at week 1, 24.01kg/m2 at week 3 (P=0.003). Waist circumference decreased between week 1 and 3 (P=0.003) and week 6 (P=0.01) by 4 cm on average. Hip circumference followed the same trend between week 1 and week 3 (P=-0.001). There was a decrease in fat mass and % fat mass between week 1, 3, and 6 (P=0.001). No changes were noted for mid-upper arm circumference or hand grip. CONCLUSIONS: The findings of this research show that even a very short duration workout affect the nutritional status in normal weight individuals who did not change any of their eating habits. This implies that even in normal weight individuals who perform the 7-minute workout, improvement through a decrease in waist circumference can be achieved thus leading to a better cardio-protective nutritional status. The 7 minutes workout can be a great solution for people to get started and to plan on continuing exercising, as it is simple and of minimal constraints.

Quality of life and coping strategies in Lebanese Multiple Sclerosis patients: A pilot study.

Coping strategies used by Multiple Sclerosis patients play a key role in adjusting to the disease and affect their overall quality of life. This relationship has been investigated in developed countries, but none has been studied in developing ones such as Lebanon. Factors including barriers to health care delivery, economic pressure and political instability influence which coping strategies are used and often increases the use of negative coping mechanisms. The current pilot study explored the association between different coping strategies with quality of life and depression, anxiety, fatigue and social support in 34 Lebanese Multiple Sclerosis patients. Results indicated that Multiple Sclerosis patients using positive coping strategies had significantly higher scores of quality of life (U=46, p=.038) and social support (U=33.5, p=.011), and lower depression (U=44, p=.030) and anxiety levels (U=46.5, p=.038) as compared to those using negative coping strategies. Specifically, escape avoidance coping strategy was associated with poor quality of life scores (r=-.609, p<.0001) and high levels of depression (r=.534, p=.001), anxiety (r=.530, p=.001), and fatigue (r=.401, p=.019). Comprehensive assessment of Multiple Sclerosis taking into account coping strategies is needed to develop proper therapeutic interventions which increase quality of life. Future studies are required to confirm these results.
